English Editing

Papers must be in English. Oxford English Dictionary or American spelling is acceptable, provided usage is consistent within the manuscript.

Manuscripts that are written in English that is ambiguous or incomprehensible, in the opinion of the Editor, will be returned to the authors with a request to resubmit once the language issues have been improved. This policy does not imply that all papers must be written in "perfect" English, whatever that may mean. Rather, the criterion will require that the intended meaning of the authors must be clearly understandable, i.e., not obscured by language problems, by referees who have agreed to review the paper.

Authors for whom English is a second language may choose to have their manuscript professionally edited before submission to improve the English. A list of independent suppliers of editing services can be found at Japanese authors can also find a list of local English improvement services at All services are paid for and arranged by the author, and use of one of these services does not guarantee acceptance or preference for publication.

Writing Abstracts

An abstract is a concise summary of the whole paper, not just the conclusions. The abstract should be no more than 250 words and convey the following:
1. An introduction to the work. This should be accessible by scientists in any field and express the necessity of the experiments executed
2. Some scientific detail regarding the background to the problem
3. A summary of the main result
4. The implications of the result
5. A broader perspective of the results, once again understandable across scientific disciplines

It is crucial that the abstract convey the importance of the work and be understandable without reference to the rest of the manuscript to a multidisciplinary audience. Abstracts should not contain any citation to other published works.

Reference Style and EndNote

References should be cited by superior numbers and listed at the end of the paper in the order in which they appear in the text. Authors should generally cite available published work, but if it is necessary to cite unpublished work, publications in press or personal communications, sufficient detail should be given for the reader to be able to follow up such a reference. References should be listed in the following style:

Illustrations and ChemDraw Rules

Upload each figure as a separate file in either .tiff or .eps format, with the figure number and the top of the figure indicated. Compound figures e.g. 1a, b, c should be uploaded as one figure. Tints are not acceptable. Lettering must be of a reasonable size that would still be clearly legible upon reduction, and consistent within each figure and set of figures. Where a key to symbols is required, please include this in the artwork itself, not in the figure legend. All illustrations must be supplied at the correct resolution:

  • Black and white and photos - 300 dpi
  • Graphs, drawings, etc - 800 dpi preferred; 600 dpi minimum
  • Combinations of photos and drawings (black and white and colour) - 500 dpi

Tables should be part of the the main document and should be placed after the references. If the table is created in excel the file should be uploaded separately.

Chemical structures should be prepared in ChemDraw either 80mm (one column) or 175mm (two column) widths. However, the one-column format should be used whenever possible as this allows greater flexibility in the layout of the manuscript. Use this ChemDraw Download or use the following settings:

Colour policy

When the use of colour in the printed journal is considered scientifically necessary by the Editors, the costs of colour reproduction may be waived. For reviews, all costs for colour illustrations will be waived; for other submissions, two colour illustrations per article will be printed free of charge and each additional colour illustration will be charged at a fixed tariff to the author. In the online version of the journal there is no limit to the number of colour illustrations permitted. Authors should be aware that for a significant number of people the colours red and green are difficult to differentiate and so these colours should not be used to create contrast.

Supplementary Material

Authors may submit supplementary material alongside their manuscript. This facility should be used for data or results which are too detailed or lengthy to appear in the printed journal, but which might nevertheless be of interest to other researchers. On acceptance of the manuscript the supplementary material will be made available on the MRC website, and an indication that additional material is available will be included in the printed paper.

The nomenclature, symbols and abbreviations adopted by the International Union of Pure and Applied Chemistry (IUPAC) must be used for chemical terminology and compound names. Well-established trivial names may be used. Atom numberings should follow the generally accepted rules and should be indicated in a formula scheme. If, for any reason, the authors choose to change the numbering scheme, this should be explained in the text and the accepted numbering must also be given.

Abbreviations and Terminology

All abbreviations and acronyms should be defined the first time they are used unless they are in such common use as to make such definitions superfluous. A list of common abbreviations and acronyms which do not need to be defined is maintained below. Terms such as PMR and CMR are not acceptable: to avoid ambiguity use 1H NMR, 13C NMR. “Multinuclear NMR” is unacceptable and should be written as “Multinuclear magnetic resonance”.

Despite their continued use in the literature, the use of the historic terms such as “upfield” and “downfield” are not acceptable in this journal; alternative terms such as “low-frequen¬cy/high-frequency” or “shielding/deshielding” should be used instead. In 13C NMR data the number of hydrogen atoms attached to carbons should not be indicated by multiplicities (s, d, t, q) but as C, CH, CH2, or CH3.

The Experimental section should be precise, and give all details necessary to repeat the work. For solution-state NMR the relevant ASTM Standard, ASTM E386 - 90(2004), should be followed (see Where new compounds are discussed, they must be fully characterized in the normal manner including spectral data other than NMR. In the case of natural products the source (e.g. the organism), the isolation procedure and a specimen deposit should be noted.

For NMR spectra, all shifts should be given on the delta scale in ppm, high-frequency shifts being denoted as more positive values. Both 1H and 13C shifts should be referenced to internal tetramethylsilane (TMS). Isotope shifts may be given in ppb. All J values should be expressed in Hz.

The following spectral details should be provided: nucleus and frequency (MHz); instrument; solvent and concentration (mg ml−1 or mmol ml−1); reference standard; temperature; pulse conditions; computer processing techniques; accuracy of parameters. Where spectral data are reported, the digital resolution must be cited, preferable in terms of spectral widths and the sizes of the data tables.

Routine two-dimensional experiments should be described by literature references as far as possible and/or by referring to standard pulse sequences and parameters provided by the spectrometer manufacturers. Where novel two-dimensional techniques are used the following details should be provided: pulse sequence including all flip angles, all delay values, and full phase cycling (preferably in tabular form); spectral widths in f1 and f2; number of t1 increments; number of data points measured per increment; number of transients acquired per increment; weighting functions (if any) in t1 and t2; data matrix size after Fourier transformation; data presentation mode (phase sensitive, absolute value, etc.); total duration of experiment. Further details should be given where appropriate.

For continuous wave EPR spectra the following details should be provided: frequency/band; instrument; field range/centre field; field sweep rate; sample phase or solvent used; temperature; modulation amplitude; modulation frequency; microwave power. For pulse EPR the relevant additional parameters should be given. Where EPR spin-Hamiltonian parameters are extracted from spectra by simulation methods, the software used should be specified, along with the parameters, such as linewidths and lineshapes, used in the analysis.

Relevant papers in recent issues of the journal should be inspected in case of doubt.

Presentation of Spectral Assignments and Evidence

Signal assignments, and the evidence on which they are based, should appear once only in the manuscript, for example in the text, in a figure or in a table. Such assignments should only be discussed in the text where they are crucial to the conclusions being drawn. Data from routine NMR experiments should not be described in detail but presented in tables or figures. The attention of authors is drawn to the fact that tabulated data are more suitable for electronic searching than are data presented in figures.

Illustrations of Presentation of Spectra

All schemes, figures and spectra should be supplied at the intended size for printing i.e. either 85 mm wide if the figure is to span one column, or 176 mm wide if the figure is to span the entire page. Lettering must be of a size that will be clearly legible and must be consistent within each figure and across all of the figures in the submission. For figures drawn at full size lettering of between 8 pt and 10 pt is suitable. Where a key to symbols is required, please include this in the artwork itself, not in the figure legend. Extraneous information, such as the authors’ names, figure captions or other text should not be included within the figure; the figure captions should be part of the main text. Unless they are essential to distinguishing different elements within the same figure, boxes and frames should not be drawn around figures or graphs.

If it is necessary to scan spectra in order to produce a diagram, authors should be aware that only high-quality and high-contrast originals are likely to produce acceptable results; the scanning resolution must be set to at least 600 dpi.

Article formats published in MRC

Reviews. Full and comprehensive reviews are welcome, as are accounts of recent developments in a particular field. Reviews, in general, should offer a broad and accessible précis of a topic. There are no formal limits on article length but they should typically contain in excess of 70 references. Reviews are encouraged and may be submitted without prior consultation with the Editors. There are no formal limits on the number of pages or images for reviews. Figures for review articles will be published colour in with no cost to the author.

Mini reviews. The criteria for mini reviews are the same as for a full review albeit less extensive in length and scope. There are no formal page limits for mini-reviews although they are typically characterised as containing under 50 references. Figures for mini-review articles will be published in colour in with no cost to the author.

Tutorials. Tutorial articles provide a source of information that goes beyond that conveyed in a normal research or review article. Topics should be presented at an introductory level suitable for non-experts with maximum attention being given to clarity of expression, freedom from jargon, and high quality figures. Articles should stimulate and inform the readers. There are no formal limits on the number of pages or images for tutorial articles. Figures for tutorial articles will be published in colour in with no cost to the author.

Historicals. Historicals are an extensive, largely narrative article , reporting an influential development in the field. This could be the development and influence of instrumentation, the impact of a technique or the contribution of a particular research group or individual . Historicals should be written in an accessible form. The Historical should be formatted as an extended editorial (no abstract). There are no formal limits on the number of pages or images. Figures for historical articles will be published in colour in with no cost to the author.

Spotlights. A Spotlight is a short article, generally under 4 journal pages highlighting a current, controversial or exciting development in the field. Spotlights may include transcript interviews with key players and balanced opinion points or discuss the future trajectory of the topic together with the immediate impact and importance. Spotlights should be written in a very accessible journalistic “newsy” style. Spotlights will be subject to screening for appropriateness and accuracy but will not undergo the traditional peer review model. Figures for spotlight articles will be published colour in with no cost to the author.

Perspectives. A Perspective is a lightly referenced scholarly opinion piece about current or future directions in a field. A Perspective can serve to assess the science directly concerned with a particular topic or report on relevant issues that may arise from the discipline (for example, policy, effects on society, regulatory issues and controversies). Perspectives that address interdisciplinary research areas or experimental results with significance to a broader audience are of particular interest to the Editors. A Perspective does not contain an abstract and generally contains less than 20 references. Perspectives will be subject to screening for appropriateness and accuracy but will not undergo the traditional peer review model. Figures for perspective articles will be published in colour in with no cost to the author. Perspectives do not contain an abstract.

Rapid communications. These describe particularly novel results or methods which merit rapid publication. Such papers will be significantly shorter than Research articles typically covering two pages in the printed journal.

Research articles. these describe the results of a particular research project, the development of new techniques, or the application of such new techniques.

Letter - application notes are short articles reporting on innovative applications, "kitchen tips" from a laboratory setting or technology. Application notes are not advertorials but are welcomed from both product manufacturers and independent authors. There are no formal limits on the length of application notes although typically they would cover no more than 4 journal pages. Application notes do not contain an abstract.

Letter - case report is an initial “in the field” or lab discovery. They should not contain more than 20 references and typically cover 2 journal pages. Articles in this category will be subject to screening for scientific accuracy but will not undergo traditional peer review models, they require no accompanying abstract.

Letter - spectral assignments. Examples of material which might be appropriate for this type of publication include: compilations of experimental data from less common nuclei, compilations of experimental data on new or unusual families of compounds, unusual spectral features, experimental data on new chemical skeletons, use of theoretical or computational predictions alongside experimental data. Spectral assignments do not contain an abstract.

The purpose of the Letter - spectral assignment article type is to report highly precise NMR data. The spectra,especially the 1H spectra, should be a) of high quality and b) uploaded as Supplementary material.

Authors must give the systematic names of the new compounds.

When configuration and/or conformation of small molecules are discussed based on NMR data, authors must provide figures of 3D structures and experimental information supporting the stereochemical assignment (NOE, J couplings, Residual Dipolar Couplings, etc.).

Authors should make their best attempt to determine the correct multiplicity pattern and the coupling constants involved in the spin systems. Second order effects should be taken into account and it is expected that spin-system simulations are to report proper chemical shifts and coupling constants. Both commercial and freeware NMR processing software can be utiltized for this purpose.

Multiplicities should not be reported based solely on peak shapes, such as a triplet-like signal (more accurately a doublet of doublets due to the corresponding proton coupling to two non-equivalent protons). The rule 2In+1, where “I” corresponds to the spin number, only applies to the J coupling of a particular nucleus (or a set equivalent nuclei) to an “n” number of chemically equivalent nuclei, such as in the case of acyclic compounds with free rotation.

For Example, please, see below.

Table 1

J coupling constant values must not be reported where the precision is smaller than the spectral digital resolution. This should not be larger than 0.4 Hz/point and must be provided in the experimental section.

Manuscripts failing to comply with these requirements will be rejected without review.

Letter - correspondence. Communication to the editor regarding any aspect of Magnetic Resonance that does not fall into any of the other categories of letter may be published as correspondence. Examples might include comments on published work, or important announcement for the Magnetic Resonance community. Correspondence does not contain an abstract.
